The objective of the study is to describe an emergency procedure for left ventricle venting during veno-arterial extracorporeal life support for refractory cardiac arrest. Veno-arterial extracorporeal membrane oxygenation is widely used in refractory cardiac arrest but is characterized by an increase in left ventricle afterload, which may impair cardiac contractility improvement. Different left ventricle venting techniques are available. ⋯ We were able to withdraw extracorporeal life support organization on day 10 and discharged on day 54. Clinical explorations reveal a fulminant rocuronium-related hypersensitivity myocarditis. This salvage surgical technique using a modified central veno-arterial extracorporeal membrane oxygenation cannulation technique has efficiently decreased blood stasis and permitted rapid recovery.

Comparative Study Observational Study
Differential modulatory effects of Propofol and Sevoflurane anesthesia on blood monocyte HLA-DR and CD163 expression during and after cardiac surgery with cardiopulmonary bypass: a preliminary randomized flow cytometry study.
The increase of the anti-inflammatory CD163highHLA-DRlow blood monocyte subset is one of the mechanisms dampening inflammation during cardiac surgery with cardiopulmonary bypass. We evaluated the effect of two different anesthetic protocols, intravenous Propofol infusion or Sevoflurane-gas administration, on the perioperative frequency of this subset. ⋯ Propofol seems to induce a higher postoperative fraction of the CD163highHLA-DRlow monocyte subset. This could represent either a compensatory mechanism dampening the higher inflammatory condition observed with Propofol at T2 or a consequence of a higher postoperative Propofol-induced hemolysis.

Comparative Study Observational Study
The effect of extracorporeal cardiopulmonary resuscitation in re-arrest after survival event: a retrospective analysis.
The objectives of this study were to 1) identify the risk factors for predicting re-arrest and 2) determine whether extracorporeal cardiopulmonary resuscitation results in better outcomes than conventional cardiopulmonary resuscitation for managing re-arrest in out-of-hospital cardiac arrest patients. ⋯ Alternative methods that reduce the advanced cardiac life support duration should be considered to prevent re-arrest and attain good outcomes in out-of-hospital cardiac arrest patients. Extracorporeal cardiopulmonary resuscitation for re-arrest tended to show a good outcome compared to conventional cardiopulmonary resuscitation for re-arrest. Avoiding or immediately correcting hypotension may prevent re-arrest and improve the outcome of re-arrested patients.

Post-cardiac arrest survivals remain low despite the effort of cardiopulmonary resuscitation. Utilization of extracorporeal membrane oxygenation during cardiopulmonary resuscitation (extracorporeal cardiopulmonary resuscitation) can provide immediate cardiovascular support and potentially improve outcomes of patients with cardiac arrest requiring cardiopulmonary resuscitation. There is renewed interest in the use of extracorporeal cardiopulmonary resuscitation due to improved outcomes over the years. ⋯ Over years of experience with extracorporeal membrane oxygenation, the outcome of the extracorporeal cardiopulmonary resuscitation has been improving and appears to exceed those of traditional methods, despite limited sample size. Neurological complications still need to be addressed in order for survival and outcomes to improve.

Randomized Controlled Trial
Pilot study evaluating a non-titrating, weight-based anticoagulation scheme for patients on veno-venous extracorporeal membrane oxygenation.
There is no universally accepted algorithm for anticoagulation in patients on veno-venous extracorporeal membrane oxygenation. The purpose of this pilot study was to compare a non-titrating weight-based heparin infusion to that of a standard titration algorithm. ⋯ In this pilot study, a non-titrating, weight-based heparin infusion appears safe and as effective in preventing veno-venous extracorporeal membrane oxygenation circuit thrombotic complications as compared to a titration algorithm. Larger studies are needed to confirm these preliminary findings.
